EMBROIDERY ATTACHMENT FOR SEWING-MACHINES.-

SPECIFICATION forming part of Letters Patent No. 250,037, dated November 22, 1881.

Application filed February To all whom it may concern:

Be it known that I, GEORGE \N. BAKER, of Cleveland, in the county of Ouyahoga, State of Ohio, have invented a new and useful Improvement in Embroidery Attachments for Sewing- Machines; and I declare the following to be a full, clear. and exact description of' the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this My invention consists in a novel combination, in a sewing-machine attachment, of devices for forming chain-loop embroidery, and for laying the same in position to be stitched to a fabric bythe stitching-needle of a sewingmachine, as will be hereinafter fully described, and pointed out in the claim.

In the drawings, Figure 1 is a front view, showing the hooked needle with the previous loop strung back upon its shank and ready to take a new loop. Fig.2 is the same, showing the new loop formed and the previous loop passed off the needle over the newloop. Fig. 3 is aview at right angles with the other views. Fig. 4 isaview of the chain-loop formed by the embroidering attachment, and showing, also, a few sewing-machine stitches, by which the embroidery is simultaneously sewed to the goods.

A is a sewing machine, B, the needle-bar; C, the pressure-bar, all of ordinary construction, the peculiar construction of the machine constituting no part of this invention.

My embroidery attachment is constructed as follows:

D is a frame or bracket, adapted to be fastened at d to the pressure-bar or its foot.

D is a projecting arm. At (1 is pivoted a lever, E, the lever-arm E of which projects down to the vicinity of the needle and close to the fabric, and is provided with an eye for the embroidery-thread at its extremity. A short arm, E projects so as to engage with a lug on the looper-bar.

F is a bar, which for the purposes of this specification I term the looper-bar. It is pivoted at f to the bracket D, and is provided with a cam-slot, f, which engages with a stud, F, projecting from the needle-bar. At the lower end of the looper-bar is a needle con- 15, 1881. (No model.)

vance and recede from side to side as the needle-bar is operated. The looper bar has a log, f which engages with the short arm E of the lever E. A spring, H, brings the lever E back when it has been deflected by the lugf A tension device may be provided upon the attachment for the embroidery-thread, though it is not absolutely essential that it should be provided on the attachment. The one shown in the drawings I have found in use to be very effective. It consists of a swelled washer, J, a spring, J, screw-stem J and tension-nut J there being nothing new in the construction of it.

The operation of the device will now be understood. The attachment having been applied to the machine and threaded, as shown, with the embroidery-thread K, the machine is started. The needle, in descending through the fabric, causes the embroidery-needle Gr to cross over to the left and back of the needle. Its hook engages the thread K, and as the nee dle rises draws it back, forming a loop. At the same time the lever-arm E advances in the direction of the feed, carrying the thread K with it, so that when the needle again descends it passes down back of the thread, and so stitches it to the fabric. As the needle, however, descends the embroidering-needleGagain crosses over to the left, again engages the thread K, and at the same time, by passing through the loop already upon it, strings the latter back upon the heel of the needle. Now, as the needle B rises the embroidery-needle is again drawn back with its new loop, and as the needle draws out through the loop at its heel this latterloop comesin contact with thelittle catch g, tilts the latter over so as to cover the hook and permit this first loop to pass off over the new loop. By a repetition of the operation a third loop is formed, the second loop forces back the latch g, takes its place at the heel of the needle G, and then, sliding forward, closes down the latch and passes off into the second loop, and so on, thus makingacontinuous chainloop embroidery, while the machine continually stitches it to the fabric as rapidly as formed.

It is apparent that it the fastening-thread be ofa different color the stitches will constitute a very marked ornamental constituent of the embroidery. So, also, whether of the same or of a different color. It'it is large it will assist materially, as shown in Fig. 4, in making, with the regular chain-loop embroidery, a heavy and handsome combination.

In case the operator should desire to make simply the embroidery for use elsewhere, all that need be done is to remove the sewing-machine threads and use only the embroiderythread. The machine will then make the embroidery alone, and without stitching it to the fabric, and it can be used where desired. It is not essential that this should be attached to the pressure-bar, for it may be connected with any other partas, forinsta ncc, the head of the machine. I prefer, however, to attach it to the pressure-bar, for it then always has the same relative position with respect to the goods, 25 whether the latter be thick or thin.

I am aware that there has heretofore been combined with a sewing-machine an embroidery attachment connected with the pressurebar and needle-bar, and arranged to lay chainloop embroidery-stitches in position to be sewed to a fabric by the stitching-needle, and I do not claim such invention, broadly.

What I claim islhe combination, with the needle-bar having 5 the laterally-proj ecting stud, of the slotted looper-bar pivoted to a fixed support and carrying at its lower end the latch-needle, its upper end being provided with a lug,f, and the pivot-ed leverE, having the arm E in the path of said lug, and carrying the thread-arm E, substantially as described.

In testimony whereof Isign this specification in the presence of two witnesses.

GEORGE W. BAKER.
